Customer Questions and Answers for Dishwasher Pump And Motor Assembly by Whirlpool

Hi Joseph. 1.The heating circuit has a open device. Heater, connection, faulty heater drive circuit on the control board. 2. Wash pump not pumping water past the heater efficiently. 3. Door switch not making contact consistently:¦ Faulty or sloppy door latch assembly (which can be aggravated by high door closure force keeping strike plate from fully seating).¦ Faulty door switch (high resistance).NOTE: Neutral switch on plastic tub models is only in series with motor and heater; other loads are not affected. 4.Lack of water to heat. Check the float switch to see if the stem freely rides up and down on the float switch. disconnect power and see if the door switches are opening and closing with a ohm meter. Check the mechanical operation of the striker and latch assy. Is the pump clear and the impeller working ? Is the pump windings OK. Measure the heater resistance. Running Diagnostics clears the control and allows it to operate again. The water heating problem must be fixed or the control will stop running again. See potential causes below. Use the tech. sheet supplied with the unit under the kick plate and or behind the door panel. If the unit allows the field service test, this will pinpoint the area in which the circuit is an Issue. Thank You.
